Linh worked on the LifeSG/react-design-system repository, focusing on maintainability and reliability in front-end components. Over two months, Linh refactored the Schedule Week View to remove unused event handlers and standardized styling with theme constants, improving code clarity and future scalability. Using React, Styled Components, and TypeScript, Linh ensured UI consistency and easier iteration across the design system. In addition, Linh enhanced unit tests for the Drawer component by introducing asynchronous waits and keyboard accessibility checks, which reduced regression risk and improved test coverage. The work demonstrated a methodical approach to code hygiene, theming, and robust UI testing practices.

September 2025: Strengthened UI reliability in LifeSG/react-design-system by delivering enhanced Drawer tests. Key features delivered: Drawer component unit tests updated to improve reliability and coverage with async waits; Escape-key close test added to validate interactive behavior. Major bugs fixed: none reported this month. Overall impact: higher test stability, reduced regression risk for Drawer-related changes, enabling faster and more confident releases. Technologies/skills demonstrated: test automation, asynchronous UI testing, keyboard-accessibility validation, and traceability through commit f0b1ec606836990261721eacd59daabf36cc220f.
